Build a world, one cue at a time.

The fundamental building block of a QLab workspace is the cue. What is a cue? Well, a cue might play a sound, or start another cue. A cue might adjust the volume of a sound, or play a video, or do nothing but wait for a particular length of time. In fact, a cue is just about anything that can be started and stopped.

In QLab, every cue is a plugin. Adding new types of cues is as simple as dropping them into your QLab plugins folder...but you don't even have to do that! QLab features integrated plugin management, allowing you to find, install and update plugins with only a few clicks.
